Can critical care transport be safely reduced in children intubated during emergency management of status epilepticus in the United Kingdom: a national audit with case-control analysis.

OBJECTIVE: This study describes the baseline clinical characteristics, predictors of successful extubation at referring hospitals and short-term outcomes of children intubated for status epilepticus and referred to United Kingdom (UK) paediatric critical care transport teams (PCCTs). DESIGN: Multicentre audit with case-control analysis, conducted between 1 September 2018 and 1 September 2020. SETTING: This study involved 10 UK PCCTs. PATIENTS: Children over 1 month of age intubated during emergency management for status epilepticus (SE), referred to UK PCCTs. Patients with trauma, requiring time-critical neurosurgical intervention or those with a tracheostomy were excluded. INTERVENTIONS: No interventions were implemented. MEASUREMENTS AND MAIN RESULTS: Out of the 1622 referrals for SE, 1136 (70%) were intubated at referral. The median age was 3 years (IQR 1.25-6.54 years). Among the intubated children, 396 (34.8%) were extubated locally by the referring team, with 19 (4.8%) requiring reintubation. Therefore, the overall rate of successful extubation was 33% (377/1136). There was significant variation between PCCTs, with local extubation rates ranging from 2% to 74%. Multivariable analyses showed region/PCCT, contributing diagnosis, acute changes on CT, preceding encephalopathy and type of continuous sedation (midazolam) used postintubation were significantly associated with transfer to a critical care unit. CONCLUSION: This study highlights wide regional variation in early extubation practices. Regions with high successful extubation rates have established extubation guidelines from PCCTs. Successful extubation represents critical care transports that have been avoided.

A Review of Materials and Medications with Religious or Dietary Significance in the Interventional Radiology Suite.

A holistic approach to patient-centered care should include cultural and religious considerations. Certain cultural groups have beliefs that may restrict the use of particular animal-derived products and chemicals. A working knowledge of ingredients commonly used in the interventional suite with religious and cultural connotations may be helpful. This review article highlights medications and medical devices with cultural or religiously sensitive ingredients used in interventional radiology departments and provides a framework for addressing this common scenario.

Combined autologous blood patch-immediate patient rollover does not reduce the pneumothorax or chest drain rate following CT-guided lung biopsy compared to immediate patient rollover alone.

PUPROSE: The purpose of this study was to evaluate a combined autologous blood-patch (ABP)-immediate patient rollover (IPR) technique compared with the IPR technique alone on the incidence of pneumothorax and chest drainage following CT-guided lung biopsy. METHODS: In this interventional cohort study of both prospectively and retrospectively acquired data, 652 patients underwent CT-guided lung biopsy. Patient demographics, lesion characteristics and technical biopsy variables including the combined ABP-IPR versus IPR alone were evaluated as predictors of pneumothorax and chest drain rates using regression analysis. RESULTS: The combined ABP-IPR technique was performed in 259 (39.7 %) patients whilst 393 (60.3 %) underwent IPR alone. There was no significant difference in pneumothorax rate or chest drains required between the combined ABP-IPR vs IPR groups (p =.08, p =.60 respectively). Predictors of pneumothorax adjusted for the combined ABP-IPR and IPR alone groups included age (p =.02), lesion size (p =.01), location (p =.005), patient position (p =.008), emphysema along the needle track (p =.005) and lesion distance from the pleura (p =.02). Adjusted predictors of chest drain insertion included lesion location (p =.09), patient position (p =.002), bullae crossed (p =.02) and lesion distance from the pleura (p =.02). CONCLUSION: The combined ABP-IPR technique does not reduce the pneumothorax or chest drain rate compared to the IPR technique alone. Utilising IPR without an ABP following CT-guided lung biopsy results in similar pneumothorax and chest drain rates while minimising the potential risk of systemic air embolism.

An 8-year, single-centre experience of primary image-guided insertion of 'button' gastrostomy catheters: Technical and clinical results.

INTRODUCTION: 'Button' gastrostomy insertion is traditionally a two-step procedure with an initial longer gastrostomy tube inserted followed by placement of the shorter 'button' gastrostomy in 6 weeks when the track is mature. The aim of this study is to assess whether the placement of a Button gastrostomy de novo is a safe and effective method of radiologically inserted gastrostomy (RIG) insertion. METHODS: Using our Picture Archive and Communication System (PACS) and electronic patient charts we identified all patients who underwent primary 'button' gastrostomy over an 8-year period with at least a 1-year follow-up period. We evaluated technical success rate, indications for insertion, major and minor complications, 30-day mortality and the number of exchanges performed. RESULTS: Overall, 482 patients underwent a primary button RIG insertion during this period with an overall success rate of 97.1%. Indications for RIG insertion included neurological and neurosurgical disorders 236 (48.9%), head and neck malignancy 182 (37.8%), oesophageal malignancy 27 (5.6%) and other indications in 37 (7.7%). The mean age was 59.55 years (range 18-88 years) with 290 men (60.2%) and 192 women (39.8%). Major complications were recorded in 0.8% and minor complications in 1.7%. A 30-day mortality of 1% was identified (five patients), mortality was directly related to the RIG insertion in one patient (0.2%). A total of 65 exchanges/replacements took place over this period of time, with 33 (50.1%) due to 'inadvertent removal'. CONCLUSION: Primary button RIG insertion is a procedure that has a high success rate and low morbidity and mortality. We believe it is a safe and effective alternative to deliver enteral nutrition.

How to Be Irish in an Epidemic: A Dossier Article on HIV and AIDS in Ireland, Then and Now.

This dossier article contains four short and varied contributions from activists and other service and healthcare providers who have been agitating and working on the frontlines of HIV/AIDS in Ireland since the early 1980s. The dossier contains: (1) a history, by Bill Foley, of the early collective efforts of a group of gay men to provoke government action and healthcare under the umbrella of Gay Health Action (GHA) (2) a speech delivered by Dr. Erin Nugent to government officials on the re-branding of HIV Ireland in 2015; (3) a brief history, recounted by Noel Donnellan, of ACT UP Dublin since it was revitalized in 2016 by a small cohort of dedicated activists from a dormant group into a vibrant collective that has achieved great legislative change with regards to pre-exposure prophylaxis (PrEP); and (4) a polemic, written by Thomas Strong, on living with HIV as a queer man in Ireland that demonstrates the ways in which HIV stigma not only thrives in but molds and shapes twenty-first-century gay men's communities, both in real life and online.

Quantitative Airway Assessment of Diffuse Idiopathic Pulmonary Neuroendocrine Cell Hyperplasia (DIPNECH) on CT as a Novel Biomarker.

Objectives: Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH) occurs due to abnormal proliferation of pulmonary neuroendocrine cells. We hypothesized that performing a quantitative analysis of airway features on chest CT may reveal differences to matched controls, which could ultimately help provide an imaging biomarker. Methods: A retrospective quantitative analysis of chest CTs in patients with DIPNECH and age matched controls was carried out using semi-automated post-processing software. Paired segmental airway and artery diameters were measured for each bronchopulmonary segment, and the airway:artery (AA) ratio, airway wall thickness:artery ratio (AWTA ratio) and wall area percentage (WAP) calculated. Nodule number, size, shape and location was recorded. Correlation between CT measurements and pulmonary function testing was performed. Results: 16 DIPNECH and 16 control subjects were analysed (all female, mean age 61.7 +/− 11.8 years), a combined total of 425 bronchopulmonary segments. The mean AwtA ratio, AA ratio and WAP for the DIPNECH group was 0.57, 1.18 and 68.8%, respectively, compared with 0.38, 1.03 and 58.3% in controls (p < 0.001, <0.001, 0.03, respectively). DIPNECH patients had more nodules than controls (22.4 +/− 32.6 vs. 3.6 +/− 3.6, p = 0.03). AA ratio correlated with FVC (R2 = 0.47, p = 0.02). A multivariable model incorporating nodule number, AA ratio and AWTA-ratio demonstrated good performance for discriminating DIPNECH and controls (AUC 0.971; 95% CI: 0.925−1.0). Conclusions: Quantitative CT airway analysis in patients with DIPNECH demonstrates increased airway wall thickness and airway:artery ratio compared to controls. Advances in knowledge: Quantitative CT measurement of airway wall thickening offers a potential imaging biomarker for treatment response.

A single center 9-year experience in IVC filter retrieval - the importance of an IVC filter registry.

BACKGROUND: To evaluate Inferior vena cava (IVC) filter retrieval practices over a 9-year period at an academic hospital with a prospectively maintained IVC filter registry. METHOD: An IVC filter registry was maintained prospectively within our institution. We reviewed cases between August 2011 and June 2020, following filter status, retrieval plans, and eventual retrieval date. The validity of the database was cross referenced with a Picture Archiving and Communication System and patient records. RESULTS: Three hundred forty-three patients had IVC filters inserted. Three filter types were used, Celect (Cook Medical) in 189, Gunther Tulip (GT) (Cook Medical) in 65, ALN (ALN) in 89. 196 (57%) filters were retrieved, 108 (31.5%) were made permanent, 36 (10.5%) died before retrieval, and 3 (1%) were yet to be retrieved. Retrieval rates were 92.5% overall (86% for GT, 93% for Celect and 94.5% for ALN). The mean dwell time for successful retrieval was 59 days with the majority of insertions (85%) removed in under 100 days. Failed initial retrieval occurred in 23 patients, 10 (43%) were retrieved at second attempt, 13/23 filters remained in-situ and were deemed permanent. CONCLUSION: The removal of IVC filters, when indication for insertion has past, is no longer the sole responsibility of the referring physician but also the responsibility of the Interventionalist. Our retrieval rates of 92.5% of eligible IVC filters highlights the value of maintaining a prospective IVC filter registry.

HIV and AIDS in Irish Theatre: Queer Masculinities, Punishment, and 'Post-AIDS' Culture.

This essay provides a critical survey of key Irish theatre productions that present queer men with HIV or AIDS as a central theme while also seeking to situate several of these productions within the controversial discourse of 'post-AIDS' as it plays out in Irish cultural and social discourses. Through this survey, this essay finds and critically elaborates how a discourse of AIDS as punishment is a common denominator in all of these plays; whether that be as a central metaphor in the drama or conversely as a trope that theatre makers seek to disrupt. Throughout, this essay simultaneously attends to the ways in which non-realist, non-linear dramatic structures (as opposed to social realist narratives) have proved to be better positioned to present the realities of living with HIV or dying with AIDS in Ireland since the emergence of the first Irish AIDS epidemic in 1982. By approaching 'post-AIDS' discourses through the lens of HIV and AIDS in Irish theatre, this essay critically analyses the insidious ways in which 'post-AIDS' Irish culture is bound up with neoliberal discourses of homonormative assimilation and cultural respectability, especially the figuring of HIV/AIDS as punishment for non-assimilation.

Multidisciplinary management of spinal aneurysmal bone cysts: A single-center experience.

OBJECTIVE: The management of spinal aneurysmal bone cysts (ABCs) is complex and often requires multimodality therapy, including surgical intervention to stabilize the axial skeleton, and avoid neurologic injury or death. With en bloc resection, ABCs have a recurrence rate of 12%, which increases to >50% with subtotal resection. The use of doxycycline sclerotherapy has been reported to reduce the recurrence rate of non-spinal ABCs to 5% at >24 month follow-up. We retrospectively reviewed our institutional results for sodium tetradecyl sulfate (STS)/doxycycline sclerotherapy and surgical intervention for spinal ABCs, to assess our treatment paradigm for these tumors and inform our future approach to these lesions. METHODS: Three cervical, two thoracic and two lumbar spine ABCs were treated in seven patients with spine-exclusive disease at our institution from 2011 to the present. The most common presenting complaint was pain. Each patient was retrospectively reviewed for clinical symptomology, number of treatments, technique and clinical follow-up. Qualitative assessment of improvement was based on the most recent clinical evaluation. RESULTS: The cohort underwent a mean of three treatment sessions (range 2-15). All were treated with STS and/or doxycycline. Five patients underwent surgical intervention at some point, either before or following sclerotherapy. After the last sclerotherapy session, four patients reported stable or improved pain symptoms, while two reported progressive pain that required surgical intervention for that indication. One patient, who underwent both multiple rounds of sclerotherapy and surgical resection, died due to acute on chronic cervical spine collapse with cord compression and inability to control disease. CONCLUSION: We report our experience in the treatment of spinal column ABCs. Stabilization or improvement in pain was seen in four patients, while the remainder had progressive disease. Our multidisciplinary approach allows patients to receive the most appropriate treatment at presentation and thereafter, for symptom amelioration or spinal stability. Important future goals are to quantitatively assess changes in symptoms over time and to incorporate a reproducible radiographic endpoint for the assessment of treatment efficacy.

Image-guided intrathecal baclofen pump catheter implantation: a technical note and case series.

OBJECTIVE Medically refractory spasticity and dystonia are often alleviated with intrathecal baclofen (ITB) administration through an indwelling catheter inserted in the lumbar spine. In patients with cerebral palsy, however, there is a high incidence of concomitant neuromuscular scoliosis. ITB placement may be technically challenging in those who have severe spinal deformity or who have undergone prior instrumented thoracolumbar fusion. Although prior reports have described drilling through the lumbar fusion mass with a high-speed bur, as well as IT catheter implantation at the foramen magnum or cervical spine, these approaches have notable limitations. To the authors' knowledge, this is the first report of ITB placement using cone beam CT (CBCT) image guidance to facilitate percutaneous IT catheterization. METHODS Data were prospectively collected on patients treated between November 2012 and June 2014. In the interventional radiology suite, general anesthesia was induced and the patient was positioned prone. Imaging was performed to identify the optimal trajectory. Percutaneous puncture was performed at an entry site with image-guided placement of a sheathed needle. CBCT provided real-time 2D projections and 3D reconstructions for detailed volumetric imaging. A biopsy drill was passed through the sheath, and subsequently a Tuohy needle was advanced intrathecally. The catheter was threaded cephalad under fluoroscopic visualization. After tip localization and CSF flow were confirmed, the stylet was replaced, the external catheter tubing was wrapped sterilely in a dressing, and the patient was transported to the operating room. After lateral decubitus positioning of the patient, the IT catheter was exposed and connected to the distal abdominal tubing with typical pump placement. RESULTS Of 15 patients with Gross Motor Function Classification System Levels IV and V cerebral palsy and instrumented thoracolumbar fusion, 8 had predominantly spasticity, and 7 had mixed spasticity and dystonia. The mean age of patients was 20.1 years (range 13-27 years). Nine patients underwent initial catheter and pump placement, and 6 underwent catheter replacement. The procedure was technically successful, with accurate spinal catheter placement in all patients. The median hospital stay was 4 days (IQR 3-5 days). One patient had an early postoperative urinary tract infection. With a mean follow-up of 25.8 months (median 26, range 18-38 months), no CSF leakage or catheter failure occurred. One late infection due to Pseudomonas aeruginosa (requiring pump explantation) occurred at 4 months, probably secondary to recurrent urinary tract infections. CONCLUSIONS Image-guided CBCT navigation resulted in accurate percutaneous placement of the IT catheter for ITB pumps in patients with prior instrumented thoracolumbar fusion. The multimodality approach is an alternate technique that may be used for IT catheter insertion in patients with complex lumbar spine anatomy, extending the potential to provide safe, durable ITB therapy in this population.
